[Security] Bump activesupport from 5.2.0 to 6.1.3.2

[dependabot-preview]

Bumps activesupport from 5.2.0 to 6.1.3.2. This update includes security fixes.

Vulnerabilities fixed

Sourced from The Ruby Advisory Database.

Potentially unintended unmarshalling of user-provided objects in MemCacheStore and RedisCacheStore There is potentially unexpected behaviour in the MemCacheStore and RedisCacheStore where, when untrusted user input is written to the cache store using the raw: true parameter, re-reading the result from the cache can evaluate the user input as a Marshalled object instead of plain text. Vulnerable code looks like:

data = cache.fetch("demo", raw: true) { untrusted_string }

Versions Affected: rails < 5.2.5, rails < 6.0.4 Not affected: Applications not using MemCacheStore or RedisCacheStore. Applications that do not use the raw option when storing untrusted user input. Fixed Versions: rails >= 5.2.4.3, rails >= 6.0.3.1

Impact

Unmarshalling of untrusted user input can have impact up to and including RCE. At a minimum, this vulnerability allows an attacker to inject untrusted Ruby objects into a web application.

In addition to upgrading to the latest versions of Rails, developers should ensure that whenever they are calling Rails.cache.fetch they are using consistent values of the raw parameter for both

Patched versions: ~> 5.2.4.3; >= 6.0.3.1 Unaffected versions: none

Release notes

Sourced from activesupport's releases.

6.1.3.2

Active Support

• No changes.

Active Model

• No changes.

Active Record

• No changes.

Action View

• No changes.

Action Pack

• Prevent open redirects by correctly escaping the host allow list CVE-2021-22903

• Prevent catastrophic backtracking during mime parsing CVE-2021-22902

• Prevent regex DoS in HTTP token authentication CVE-2021-22904

• Prevent string polymorphic route arguments.

  url_for supports building polymorphic URLs via an array of arguments (usually symbols and records). If a developer passes a user input array, strings can result in unwanted route helper calls.

Changelog

Sourced from activesupport's changelog.

Rails 6.1.3.2 (May 05, 2021)

• No changes.

Rails 6.1.3.1 (March 26, 2021)

• No changes.

Rails 6.1.3 (February 17, 2021)

• No changes.

Rails 6.1.2.1 (February 10, 2021)

• No changes.

Rails 6.1.2 (February 09, 2021)

• ActiveSupport::Cache::MemCacheStore now accepts an explicit nil for its addresses argument.

  config.cache_store = :mem_cache_store, nil
  is now equivalent to
  config.cache_store = :mem_cache_store
  and is also equivalent to
  config.cache_store = :mem_cache_store, ENV["MEMCACHE_SERVERS"] || "localhost:11211"
  which is the fallback behavior of Dalli

  This helps those migrating from :dalli_store, where an explicit nil was permitted.

Rails 6.1.1 (January 07, 2021)

• Change IPAddr#to_json to match the behavior of the json gem returning the string representation instead of the instance variables of the object.
